Welcome to the Boneyard! In this field puzzle make sure you have the following things:
When you get to the posted coordinates look for the information sign near the entrance to the Boneyard. Take coordinates of the middle of the two poles. Be sure these are pretty good. Next, take these coordinates and add 0.030 to the north coordinates and subtract 0.032 from the west. These will lead you to the final. Good luck and happy caching!
